So i've been debating resetting my MBA to factory settings for a while and thought i'd ask here to see if it will accomplish what i'm trying to get out of it. My SSD is 128gb and is about 55% full. The majority of storage is taken up by "other storage" (about 40 gigs are in other storage, while small amounts are in audio, video, documents). I wanted to do a reset for two main reasons: 1) to hopefully get rid of the immense other storage allocation (i know some will still be there but the amount that its at seems too large) 2) just a general cleanse of my computer All my files are stored on dropbox and I can transfer my programs after a fresh install of OSX. I've already looked into and used disk cleaning programs (omni disk sweeper, etc) but none have really worked in reducing other storage space. I've read many forum threads about it (here at macrumors and elsewhere) and still don't completely understand how to see / get rid of stuff in there. When I check my folder size for my documents, applications, etc, it does not seem to be nearly as large as how much storage my computer is saying I've used. TL;DR Will a factory reset actually eliminate this "other storage" problem? Thanks for reading and your help!
